4 Free Online Tools for Examining Suspicious PDFs

In an earlier post I outlined 6 free local tools for examining PDF files . There are also several handy web-based tools you can use for analyzing suspicious PDFs without having to install any tools. These online tools automate the scanning of PDF files to identify malicious components. The list includes PDF Examiner, Jsunpack, Wepawet and Gallus.

PDF Examiner

PDF Examiner by Malware Tracker is able to scan the uploaded PDF for sveral known expoits, allows the user to explore the structure of the file, as well as examine, decode and dump PDF object contents. This tools lends itself well to manual PDF analysis tasks. In this way, it differs from Jsunpack and Wepawet, which focus on automating the analysis as much as possible.

If you merely need to know whether antivirus products identify a particular PDF file as malicious, without gaining much insight into the file’s inner-workings, you can upload the PDF to free online services that scan files using multiple antivirus engines. The options include: VirusTotal , Jotti’s Malware Scan , Filterbit and VirSCAN .
